第一位收到OPA的用户在国外论坛的意见:a-nd 应省去中间的-

Just receive your OPA - Earth a-nd Sun. Very nice packing.


First impression I must say very long lasting. I have found the sound that I miss. The earth sounds so natural and crisp clear. The separation is very good when I play the chinese high impact drums. The vocal is so natural a-nd the singer sibilance (like the Sssst, Ssssh) is gone. This is what I am looking for. It is so much better than the OPA 627, way much better.



good job. next I will test OPA Sun.

只要是这些型号，按个运放插座，将模块插上就可以了。如短开4，8脚用线连，另装的睿志并联电源板，配个好牛，单独供电会更好。

I've got the Audio-GD C-39 preamplifier for couple of months ago and been extremely satisfied with it. The naturality of the sound and the stereo "picture" of the music is very 3D and almost like tangible, what an experience!
    The technics inside of the device are just superb. Why to spend thousands (or tens of thousands) for a equal device, if you now can get a marvelous piece of equipment for less money. Btw. the build quality is excellent and the service and generally doing business with Audio-GD was just 100% fluent.

    I was very intrigue with Audio GD products, hard technology with amazing
price. So i buy a Sparrow fo-r my Ergo 2 headphones and a P1 preamplifier
with different modules fo-r my Phy HP speakers.
    I’m very impressive with the quality of these components, Sparrow is the
best headphone amplifier I heard, but I don’t heard a lot in fact… But, fo-r
P1 I compared it with Linn LK1, Luxman CL32, Brinkmann pré, Passive
Promitheus TVC, Audio Analogue Bellini and Spectral DMC 20…
    You have 2 points with high fidelity components, the association in a system
and the inner quality of the component. Audio GD P1 is a better preamplifier
than Linn LK1, Luxman CL32, Brinkmann, Audio Analogue Bellini. Mo-re silent
preamplifier, mo-re transparency and extension in high and low frequency,
mo-re natural medium too….
    Audio GD P1 is’ not better than passive promitheus TVC o-r Spectral DMC 20
but I prefer the sound of Audio GD P1 in my system. The Spectral is mo-re
detailed but too harshness in my system and the Promitheus TVC is a little
bit too “thin sounding” fo-r me.
    Only thing I can say after 20 years in high fidelity fever, the audio GD P1
is a real good preamplifier with natural sound without lack in transparency
o-r extension fo-r a bargain price… So, I find my company fo-r high fidelity
now. I’m not man who want to spend mo-re money if I can find good fo-r less
and I know that in France I have to spend 3 o-r 4 times the price to get
equal and mo-re to get better…
   Hope successful fo-r your bizness and I think that audio GD it’s a very good
choice fo-r audiophile who like quality… You know I will buy your complete
Cast line, just give me the time to get money !

My system :
   DIY speaker with Phys HP and Raven ribbons and a subwoofer with Monaco-r
rapto-r 12
   DIY amplifier with LC AUDIO Tehcnology modules in class D
   Préamplifier Audio GD P1 with M7, A50, BPM modules (at my choice)
   Dac EAD DSP 7000 MK 3 with all Noble mods
   Drive Pioneer PDS 06 with Mods

这位是澳洲的爱好者用CD3与DAC8

I had a quick listen to the system before I left for some holidays and
I'm very very impressed with the sound.
All my friends agree it has incredible transparency, very impressed with
the quality of the components used and the PCB quality.

昨天一位用旧DAC3德国爱好者的邮件:

I use your equipment with one older Teac VRDS 10SE Player, modified with your clock, an rebuilt Xiang Sheng Headphone/Pre Amp and self made speakers. In next time I will need 2 (stereo) PowerAmps because its a active solution, but in the moment I am watching your components. Your components are the best components I have seen and heard yet and I have seen a lot of hifi components.

Often I think about it to be the distributor of the European Union for your products, but if yes, it should be a very professional distribution. That is something which is really often going through my head.

The opening of your Olympic Games has been very impressive. Great!





大意如下
我现用你的器材和配用你的时钟摩改的Teac VRDS 10SE 盘,一个再做的Xiang Sheng 前级/耳筒机和自制的音箱,下次我要两台stereo功放,因为这是绩极的解决问题,

在现时我留意你的器材,我曾经听过很多hifi器材,而你的器材是我听过见过最好的!我经常很想把你的器材做欧盟代理商,如果是的话这将是最专业的代理,这经常在我的脑海中打转.

我喜欢它家的M7模块![s:20]

静听禅声

貌似不错的东东！

风吹柳花

这个还真是非常好的思路跟方法，用处大大滴。

我也曾设想过类似做法，没精力去实现.........

STK3048A，我的意思是这个东西现成的模块，比装晶体管的强。高压+-40V[s:97] 。

其实傻瓜不多，多的是愿意自己装傻瓜。
